Issue with Re-Indexing

HI,

I have tried Re-Index one of the index. While Re-Indexing, it is taking the data from other indexes as well. Have given the config file below.

input
{
  elasticsearch 
	{
		hosts => [ "localhost" ]
		index => "sanjay"
	}
}

output
{
	elasticsearch 
	{
		hosts => "localhost:9200"
                index => "MDSR"
		document_type => "MDSR"
	}
    stdout
    {
        codec => "json"
    }    
}

When I run this config file, it is taking the data from "sanjay_reddy" index as well.
Is there anything that I should change?
Please help me out :frowning:

Regards,
Sanjay Reddy M.

Could it be the case that "sanjay" is an Alias rather than an Index ?

Thanks for the reply @JoarSvensson

I haven't used any alisases in my cluster :frowning:

Alright, please note that the reindex feature in 2.4 is marked as experimental in the docs.
